Installing the Fuel Tanks, Lines, Taps and Fittings
SEE DRAWINGS FOR PARTS REQUIRED
Recommended two persons job.
1. After carefully studying the five drawings select and inspect the wing-
tanks, taps and fittings as illustrated. You will need about six metres of
fuel line. Cut the fuel line to the lengths specified allowing about 10%
extra on each length for fitting.
2. Install the wing-tanks first and then loosely connect the lines, hose-clips
and fittings following the exact sequence illustrated in the drawings.
Temporarily fix the fuel lines in position with duct-tape and trim the
lengths as required but when inserting the spigots inside the lines be
careful not to shave off a sliver of material that might eventually find its
way to the carburettors.
Note 1. Drawing 17.100 shows an under-wing
fuel vent line but there is also a “vented-cap” option not illustrated
here. Note 2. There is no water trap (gascolator) illustrated in the
drawing but a small one should be fitted in the lowest part of the fuel
line after the “T” fitting (9) to allow external access for contamination
checks. This will require a small hole to be cut in the floor panel.
3. Recheck 1 and 2.
4. Tighten the hose clips and secure the lines with cable-ties as shown.
6. Thoroughly inspect the finished work.
